BACKGROUND: Impaired motor control, balance, muscle strength, and respiratory function may affect the exercise capacity related to motor performance and activities in individuals with stroke. OBJECTIVE: To identify a physical parameter that the exercise capacity has the most significant relationship among physical parameters related to motor function, trunk control, balance, and motor performance and activities in individuals with ischemic stroke. METHODS: In total, 241 ischemic stroke patients were recruited in this retrospective study. The clinical measurements included the 6-minute walk test (6 MWT), Montreal cognitive assessment (MoCA), Fugl-Meyer assessment-lower extremity motor function (FMA-LE), trunk impairment scale (TIS), Berg balance scale (BBS), timed up and go test (TUG), 10-meter walk test (10 MWT), functional ambulation category (FAC), and functional independence measure (FIM). RESULTS: The 6 MWT was significantly correlated with the FMA-LE, BBS, TUG, 10 MWT, FAC, and FIM, indicating negative or positive moderate correlations. Additionally, the FMA-LE, TIS, BBS, TUG, 10 MWT, FAC, and FIM, excluding the 6 MWT, showed moderate to strong correlations with all of the other outcome measures, whereas the MoCA showed significant correlations only with the BBS and FIM. CONCLUSIONS: In this study, the exercise capacity has the most significant relationship with the TUG parameter in stroke patients. Additionally, we suggest that significant relationships between 6 MWT and other comprehensive physical functions measurements are closely related to walking ability in individuals with stroke.
